To all whom t may concern: f Be it known that I, LoUIs WELKER, Jr.,a y citizen of the United States, and a resident of Villiamsport, in theCounty of Lycomingv and State of Pennsylvania, have invented certain newv and useful Improvements in Window-Operating Devices; and I do hereby declare the following to be a full, clear, and" 'exact description ofthe invention, such as will enable Aothers skilled4 in the art to which it appertains to make and use the same.

This invention relates to improvements in window operating devices and more particularly to that which may be termed a sash jaeln-one object ofthe invention being to provide a simple, portable device which shall be operable in co-operation with sash lifts of different types to start the upward movenient of a sash which may have become stuck from any cause, and thus avoid suchinjury lto the sash or the pane-holding means as is liable to occur when attempt yis made toforcibly raise a sash which has become stuck by applying upward force to the top rail.

thereof, or by hammering the sash to loosen the same. I

I/Vith this object in view, the invention consists in certain novel features of construction as hereinafter set forth and `pointed n out in the claims.

Inthe accompanying drawings, Figure l is a view illustrating an application of my` invention to a window sashhaving one type of sash lift. Figure ,2 is` a similar view showing the use ofbmy improvement with an other type of sash lift, and Figure -3 is a'. sectional view on the line 3 3 of Figure 1.1

A portion of a sash l is illustrated in Figi ure l of the drawings as being provided in its bottom rail with a sash lift 2'of the coun--r tersunl; type, and in Figure 2 the sash is` shown as having a sash lift 2 ofthe projecting lip type secured thereto.

My improved sash jack comprises a saddle or support 3 which may be constructed of a single piece of metal bent in such mannery as to provide a base 4L and parallel standards 5 5, and a lever 6 pivotally vmounted a comparatively short distance from its forward end between the upper portions of the standards of said saddle or support, by means of. a pivot pin 7. The long arm of the lever provides a handle and its short arm` provides engaging means for a sash lift. In the 1921. serial No. Maasai embodiment of `my invention shown in the drawings,th`e sash lift engaging means constitutes anl integral part. of the short arm of-said lever and consistsof an upwardlyv curved portion 8.

I/Vhen the device .fis

used Vto, start ay sash provided with a sash lift 2 ofthe counter-y sunk type, the engaging kportion 8 at the 'cof forward end lof the short arm of the lever y will be inserted into thefcountersink of said lift and lmade to engage the `upper wallthereof,'so that'downward pressure on thef handle portionr vof lthe lever will cause 'the sash to be' raised a vsufficient distancevto release it; wWhen the device is employed to start a sash havingfa lift 2a, the `engaging member 8 of thelever will be placed under the lip of said lift so as'to engage the saine.

in proximity to the body portion of said'lip.` It will be observed that the engaging member of the device, lley-contacting with the lip behind the free` curved endthereof, `said engaging member is not liable to slip olf the lip and the latter `is not liable to be bent` i when pressure isl applied to raise thesash. y 8o` age maybe exerted upon thesash so that it will be quickly and easily loosened. The sharply turned terminal may be very easily engaged in the sash Vlift and will apply the power inan upward ldirection and substan` tially longitudinally .of the lifting arm of the lever instead ofacross the end of the same as is the case with devices heretofore Y suggested for the same purpose,'so that .the

sash-'lift-engaging point is not yso apt to'be 4broken off `under the lifting strain. l The` saddle is of very inexpensive construction but isv strong and durable,'provides affiat`v base -so that it will remain firmlyseated whilein usefand is o'fsuch a form that the levermay bevery easily assembled therewith]4 Havingfully described by invention what I claim as new and desire to secure by Letters-Patent, is: y

Al sash-lifting comprisingv a 'support to yrest upon a window sill and a lever pivloted near one end to said'support, the` shorter arm of -s'aid lever bein-g curved upwardly and havin its i free end portion shaped to engage an Conform approximately to the* 2 l l y 1,455,464

under'face of the `projeeling lip of' a sash specification in the presence of two suby lift and to also firmly engage the upper Wall scrbng Witnesses. of a recessed sash lift, whereby force applied upwardly by the engaging end of the lever 5 will be imparted to the sash lift close to the Witnesses:
